REFRIGERATOR-CAB.

1,030,671. Application filed November 12, 1907, Serial No.

To all whom it may concern:

Be it known that I, SYLVESTER Mason, a citizen of the United States, residing at "Willisville, in the county of Perry and State of Illinois, have invented new and useful in Refrigerator-Cars, of which the following is a specification.

This invention relates to refrigerator cats,

the object of the invention being to secure better refrigeration. than is now'to be obtained in the ordinary refrigerating cars now in common use, to render the retrigera tion of the car more economical, to afford increased. storage capacity and also to pro vide for a complete circulation of air and ventilation of and escape of heated air from the storage compartment.

A. further object of the invention is to obtain a simple, economical and eil'ective construction of car and the parts thereof which contribute to the ventilating and refrigerating capabilities thereof.

With the above and other objects in View, the nature of which will more readily appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts hereinaf ter fully described, illustrated and claimed.

In the accompanying drawings, Figure 1 is a side elevation partly in section of a refrigerator car to which this invention is shown applied. Fig. 2 is a vertical cross section thereof on the line 22 of Fig. 1. Fig. 3 is an enlarged vertical cross section through the upper portion of a car illustrating the motor and fan arrangement. Fig. 4 is a sectional plan view of the car. Fig. 5 is a detail vertical longitudinal section through the upper part of one end of the car.

The car in which this invention is cinbocied may be of any general or preferred construction and in fact the principles of the invention may be applied to cars now in general use without rebuilding the same and without extensive alterations.

1' designates the usual floor of the car. which forms the bottom of the refrigerating chamber or storage room 2. This storage Specification of Letters Patent.

form as shown at 6 and is at a suilicie'nt distance beneath the roof of the car to provide a superimposed or top ice-bin 7 to which filling openings lead through the roof of the car, said openings being closed by means of trap doors 8. Corresponding tilling openings lead through the root of the car to the end ice bins 3 and are closed by other similar trap doors 9.

Extending along the top of the storage room 2 is a plurality of air conduits 10, 11 and 12 arranged side by side and preferably close together as illustrated in Figs. 2 and 4. D At one end of the storage compartment, said air conduits extend downward as shown. in Fig. l and then horizontally beneath the floor of the car as shown in the same figure,

and. by reference to Fig. 4, it will be observed that these air conduits terminate beneath the car floor at diflerentpoints and are provided with discharge openings 13 which register with corresponding openings in the floor 1., whereby the cold air delivered from said'conduits is directed up through thelloor of the car at difllercnt points in the length of the storage compartment thus distributing the cold air throughout said compartment and through the produce 'contained therein, the heated air rising and passing through one or more slatted ventilators 14. The top runs of said air conduits which extend along the top of the storage compartment all terminate in the same tcansverse plane as indicated in Fig. 1, and extending across the receiving ends of said conduits the shaft 15 of a blast fan 16, which tan is of suiiicient length to supply air to each and all of the air conduits 10, 11 and 12 when rapidly rotated. V

The fan casing 30 extends the full width of the car body and has its ends both open to the atmosphere so that air can enter from each end as the fan rotatesand as a result all the air ducts will be amply supplied with air and. as long as the tan operatesthere will be a continuous circulation of air through the storage room since the air will flow out through the ventilator 14 as fast as fresh air is supplied by the tan.

The means tor impartingmovement to the blast fan 16 consists of a wind motor mountkaa the invention, the wind motor comprises a shaft 17, on which are mounted fans 18 partially inclosed by superimposed housings or hoods 19, which shield about one-half of each fan 18, exposing the remaining half,

preferably the lower half of such fan to the action of the current of air-,the hoods 19 being provided with inlet mouths 20 extending in opposite directions-as indicated in Fig. 1. The shaft 17 passes under the usual running .board'21 extending lengthwise and centrally ofthe top'of the car, and said shaft is rovided at one end with a sprocket whee 22 from which \a driving chain 23 extends downward around another sprocket ,wheel 24 fast 'on the blast fan shaft 15. Thus it matters not in which direction the 'car is moved, the fan 18 is subjected to the action of the air current and rotation is imparted to the blast fan 16 which directs a current of air through each of the air conduits 10, 11 and 12, the air'being distributed to different parts of the storage room of the car in the manner above described. It will be noted that as the air traverses the said conduits it becomes thoroughly chilled by reason of the contiguity of said conduits to the ice bins shown and described.

It is also desirable to make the roof of the car of double construction as indicated in Figs. 2 and 3, the said roof comprising an outer wall 25 and an inner wall or ceiling 26, leaving an interposed air space 27 be tween the same. The construction justreferred to affords a considerable protection .to the, top ice compartment and other parts of the car and economizes' in the consump-j tion of ice. I

- If desired, the side and end walls of the car and also the doors 28 may be double walled or provided with inclosed air spaces 29 and the said parts may be lined with suitable material to still further resist the-transi sprocket and sprocket chain type, it will of course be understood that spur gearing or belt gearing may be substituted for the sprocket gearing shown and described without departing from the principle of the invention.

Having thus fully described the invention,

- what is claimed as new is I 1. A refrigerator carcomprising abody provided with a storage compartment, a fan casingmounted wholly within the body and I Witnesses dependent of the fan casing, and meansmounted on the body for operatingthe fan. 2. A refrigerator car comprising a body provided with a storage compartment, a fan casing mounted wholly within the body and formed in part by one of the walls of the storage compartment, both ends of the fan casing being open to the atmosphere, a reversible fan mounted in the casing to draw air into the latter through both ends, air conduits extending from the casing to and discharging into the storage compartment, and a reversible motor mounted on the body at the outside thereof and operatively connected with the fan.

3. A refrigerator car comprisinga body provided with a storage compartment, a fan each'wheel and open at opposite sides to cause rotation of the wheels in either direction by the currents of air induced by the movement of the car.

1. A refrigerator car.comprising a body provided with a storage compartment, a fan casing extending entirely through the body and open to the atmosphere, means for conducting air from the fan casing to the compartment, a fan rotatably mounted in the casing, a shaft mounted above the body and extending from one side thereof to the other and substantially parallel with the axis of rotation of-the fan, driving means between the shaft and fan located outside the car body wind wheels mounted on the shaft at opposite sides of the longitudinal center of the car, and a hood secured to the roof of and having openings at opposite sides for permitting wind currents to rotateithe:

wheels in either direction.

In testimony whereof I aifix my signature in presence of two witnesses,v
